SPECIFICATION formingpart of Letters Patent No. '7 16,913,61ated December 30, 1902. Application filed May 2?, 1901. Serial No. (SL999. (N model.)

To a whovn it vita/y concern:

Be it known that 1, JAMES MACPHAIL, a oiti zen of the United States, residing-at Blue Island, in the county of Cook'and State of Illi 5 nois, have invented new and useful Tilting- LeverI-Iandles for Headers, of which the following is a 'specification. r

This invention relates to tilting-lever handles for headers.

Theobject of the invention is to provide a handle for the tilting lever of harvesting-machines of the header class which is simple in construction and whereby said handle can be operated by the foot of the driver of the ma- I 5 chine. a

The invention consists, su bstantially,in the construction, combination, location, and ar-- rangernent of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and'finally pointed out in the appended claims.

Referring to the accompanying drawingsand to the various views and reference-signs" appearing thereon, Figure l is a View in perspectiveofaharvesting-machineof the header class, showing the application thereto of a handle for the tilting lever embodying the principles of my invention. Fig. 2 is a view in longitudinal central section of a lever-handie embodying my invention. Fig. 3 is a top plan View of thesame. Eig. .4 is an end view.

The samepart is designated by the same reference-signwherever'it occurs throughout the severalyiews.

In harvesting 'machines, and particularly machines of the header class, it is the usual custom to pivotally mount the frame of the machine upon the main axle of the traction- 40 wheels and to provide such framework with a tilting lever arranged to extend rearwardly or into convenient position to be actuatedby the driver of the machine, whereby the frame may be tilted upon the axle. It is also one tomary to provide such tilting lever with an operating-handle arranged to be grasped by the hand of the driver to efiect the tilting movement thereof, said handle being provided with a' pawl arranged to cooperate with a rack, whereby said lever may be held in any desired position of adjustment. In the construction oflocking-handles for tilting levers such as has heretofore been employed in machines of this class when it is, desired to raise or lower the tilting lever it has been 53 necessary for the driver, who generally stands erect in handling or driving the machine, to stoop or bend down,'so as to be able to grasp by hand the handle and to release the locking-detect. It will be readily seen that this stooping or bending down is objectionable, for th'e reason that in accomplishing this work the drivers attention is detracted from his horses or from the proper guidance of the machine and also is inconvenient by reason of the driver having to stoop or-bend down to grasp by hand a part which is located at his feet. Itis among the special purposes of the present invention to provide a construction of handle for tilting 7o levers of headers which may be operated by the foot of the driver, thus avoiding the necessity for stooping or bending over and also avoiding the objection of detracting the at- Tention of the driver from the proper handling of the machine.

Referring to the accompanying drawings, reference-sign A designates generally the framework and various parts of a harvesting-machine of the header type; B, the main 8o axle upon which the framework of the machine is mounted; O, the traction-wheels, and

D the tilting lever for the frame. ,These parts may be of the usual or any well-known or ordinary construction and in the specific details thereof form no part of my present invention. g

Reference-sign E designates generally the i-h'andle suitably mounted on or secured to the a guard or rest for the foot of the driver.

Pivotally mounted, as at L, upon the casting and operating through a slot M in said cast- :00

ing is a locking pawl or dog N, provided with a nose P, arranged to cooperate with a ratchet bar or rod Q to hold the tilting lever in any desired position of adjustment, said ratchet or rack bar Q passing through an angular slot R of the casting and secured 'to a fixed part of the frame or tongue of the machine. A spring S may be arranged to engage behind the locking-pawl N and serves to yieldingly maintain the nose P pressed forwardly into engaging relation with respect to the rack bar Q. The pawl or dog N is provided with a tail A, having a lateral extension B, arranged in convenient relation with respect to casting F to be engaged by the heel of the driver, whereby said pawl or dog'N may be rocked about its pivot by the foot of the operator or driver to disengage the nose P thereof from engaging relation with respect to the rack-bar Q, and hence permitting the tilting movement of said lever to rock the frame about its supporting-axle and without the necessity of the driver stooping or bending over to engage the lever by hand. It will also be seen that the locking pawl or dog may also be actuated by hand when desired, and hence the casting F at its extreme rear end is provided with a handpiece 0'.

From the foregoing description it will be seen that I provide an exceedingly simple and efficient construction of handle for the tilting lever of harvesting-machines of the header class wherein the lever may be tilted and controlled as to its tilted or adjusted position by the foot of the driver.

Having now set forth the object and nature of my invention and a construction embodying the principles thereof, which is the best form in which I at present contemplate carrying my invention into practical operation, I desire it to 'be understood that many variations and changes in the details of construction would readily occur to persons skilled in the art and still fall within the spirit and scope of my invention. I do not desire, therefore, to be limited or restricted to the exact details shown and described; but

What I claim as new and useful and of my own invention, and desire to secure by Letters Patent of the United States, is

1. The combination with the tilting lever of a harvesting-machine, of a handle for such lever comprising a casting, a locking dog or pawl pivotally mounted on said casting, and

a lateral footpiece extending from said casting and arranged in proximity to said dog or pawl, whereby the latter may be manipulated by the foot of the driver resting on said lateral footpiece, as and for the purpose set forth.

2. The combination with a tilting lever for a harvesting-machine, of a handle therefor comprisinga casting having a lateral extension arranged to form a foot-piece, a dog or pawl pivotally mounted upon said casting and also provided with a lateral extension arranged adjacent to the lateral extension of said casting,'aud a rack-bar with which said dog or pawl cooperates, as and for the purpose set forth.

3. The combination with a tilting lever for harvestingmachines, of a handle therefor comprising a slotted casting, a dog or pawl pivotally mounted in the slot in said casting and provided with a tailpiece, a lateral extension formed on said tailpiece and a lateral extension formed on said casting adjacent to the lateral extension of said tailpiece, and a rack-bar with which said locking pawl or dog cooperates; all combined and arranged as and for the purpose set forth.

4. The combination with a tilting lever for harvesting-machines and a stationary rackbar, of a handle for said lever comprising a slotted casting, a locking bolt or dog pivotally mounted in the slot in said casting and provided with a nose arranged to cooperate with said rack-bar, a spring arranged to bear on said dog or pawl and normally operating to hold said nose-piece in engaging relation with respect to said rack-bar, said dog or pawl provided with a tailpiece, said tailpiece having a lateral extension, and a lateral extension formed on said casting and arranged adjacent to the lateral extension on said tailpiece, whereby the foot of the driver resting upon the lateral extension of said casting may also control the engagement of said pawl or dog with said rack-bar, as and for the purpose set forth.

In witness whereof I have hereunto set my hand, this 23d day of May, 1901, in the presence of the subscribing witnesses.
